[QUOTE="MacInWin, post: 1887711, member: 396914"] The network sharing has renamed his machine to "Jeffs-iMac-2.local" to avoid conflict with what it thinks is "Jeffs-iMac.local." Not two machines, the same one, but somehow logged into the local area net twice. I've seen it when a machine is logged in by WiFi and then connected by Ethernet. Each interface gets a separate IP, but then sharing thinks that at one IP is a machine with the same name as at the other IP and renames itself to avoid the conflict it thinks is there. What I have done is log out of both (turn off WiFi, disconnect Ethernet), then rename back to original and then turn on WiFi again and plug in the Ethernet. [/QUOTE]
